In this paper, we developed and tested comparison performance of our developed Integrated Cathodic Protection Monitor (ICPM) with other instruments. ICPM is more accurate than other products due to using high impedances(100MO) to fit high soil specific resistances. And we achieved measuring of corrosion protection voltages at the fields and comparing of those data with other instruments. We demonstrated...
Recently, we can find news about toxic and combustible gas accident. So, we have to develop gas detector that can measure gas safely at dangerous area and be possible to monitor gas detection at remote area. In this paper, we analyze and estimate gas sensor modules and combustible gas detectors that is already developed, by using standard gas sample manufactured Korea Gas Safety. We apply result analyzed...
In this paper, the developed digital excitation control system was evaluated to get the strength of operating situations in the small power plant. Recently, most automatic voltage control systems for big power plants employ a quick response and stationary excitation technology. But cost of older excitation systems has been prohibitive for redundancy. And they add much complexity to the system relative...
